CHICAGO, ILLINOIS LO CK .Application filed .Tune 15,

A further object of the Vinvention is to provide means that will not only prevent the theft of the spare wheel or tire rim, but will also prevent the theft ot a tire from the spare wheel or riin. Y

Forthe purpose oi illustration, a selected embodiment of the invention is illustrated in the accompanying drawings in which Fig. 1 is a vertical sectional view through a conventional bracket, spare wheel, rim and tire with the invention applied thereto;

Fig. 2 is an enlarged sectional View ot a portion of Fig. 1 with the lock fastening shown in section;

Figs. 3 and are sectional views taken on the lines 3--3 and 114-11 of Fig. 2, respectively;

Fig. 5 is a side elevation ot a substitute nut for use in connection with this embodiment of the invention, and Y Fig. 6 is a perspective view of a roto lock bolt for cooperating wtih the nut shown in Fig. 5.

Nothing in this illustration nor in the coi'- responding specic description is intended to require a narrow interpretation of the claims.

Referring to Figs. 1 and 2, 10 indicates a conventional bracket having a flange 11 equipped with a flanged disc 12 against which a conventional disc wheel body 13 is usually secured by a plurality of bolts 14C and nuts 15.

The wheel body is equipped witha conventional rim 16 carrying a conventional tire 17.

According to this embodiment of the in vention one of the nuts 15 is discarded and replaced by a nut 18 (Fig. having a .cluding a casing 21 having a longitudinal bore 22 to receive the nut 18, and a spring 23 adapted to be compressed between the 1927. Serial No. 198,995.

end of the nut and the bottom of the bore to prevent rattling.

The shield is also equipped with a bore 2-1 parallel to the bore 22 which is extended laterally at opposite sides by grooves 2a adapted to cooperate with tumblers 26 carried by a locl: plug 27 rotatably mounted in the bore 2e and made fast within the shield fby a split loclring ring 28 iitted in corresponding grooves in the shield and the plug. ce Adjacent to the left end in Fig. 2 the bore 2&1 is enlarged, as indicated at 29, sufficient to intersect the bore 22 and torni a mounting tor a rotary bolt 30 which is in the form ot a circular disk cut away, as indicated at 31, on an arc corresponding to the wall of the bore 22, At one side the bolt is itted with a cylindrical stein 32 which is rotatably mounted in the bore 241 and a split at 33 to cooperate with a flattened rib 34 on the plug 27, whereby the bolt and plug are made to rotate in unison.

The end ot the bore 29 is closed by a threaded disk 35, which is also cut away at 36 on an arc corresponding to the wall of the bore 22, so as not to interfere with the entry and withdrawal of the nut 20.

A key -37 controls the tuniblers 26 and serves as a handle for rotating the plug 27 and with it the bolt 30.

lVhen it is desired to lock the spare wheel or rim, or other device in place, the giooved nut 20 is applied to the bolt 14 and set up. The shield is then inserted and placed over the nut and the key 37 turned to set the bolt 30 in the position shown in Fig. 2 and then withdrawn when the tninblers 26 drop into the groove 25 and lock the plug and, hence, the bolt in that posit-ion. The shield can be freely rotated about the nut, but cannot be jammed against it so as to permit unscrewing the nut and, of course, a wrench cannot be applied tothe nut, therefore, the device is securely locked until the key is inserted to turn the bolt to the reverse ot that position, shown in Fig. 2, when the shield may he withdrawn and the lnut removed in the usual'inanner.
